[jira] [Reopened] (FTPSERVER-320) Passive Data connections are slow when using SSL

     [ https://issues.apache.org/jira/browse/FTPSERVER-320?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

-------------------------------------

      Assignee: David Latorre

I think it makes sense that we get rid of the reverse DNS lookup in the stable/1.0.x branch.  

All the other improvements by Sai are available in trunk.

> Creation of passive data sockets is slow when using SSL. The issue is that the code calls InetAddress.getHostName() method which performs a reverse name lookup. This is an expensive operation (at least on all the systems I've tried). We really don't have a need to get the host name, so change the code to get string version of the IP address and use it instead.
